These and other'objects and advantages reside in novel features'of construction; arrangement and combination of parts which will be fore fully described and pointed out in the appended claims;

Referring to the drawing:

tance between the nose pads 'is'altered.

Now referring to the modifications shown in Figures 3, 4 and '5, the

The arcuate arm 'I tensionally engages the edge engaging means and the positioning of the lug '2 are" shownin various preferred arrangements;

The lug 2 is radially connected to the The arcuate arm 1' is directed along the rear surface of the lens 3 and shaped the lens. The' rear surface 'of the le'ns 3 upon securing-the lens tothe' lug 2. The lens edge of "the lens 3 is engaged by "a continuation orthebridge ID- shownas HQ and by 'a contlnuatiorrioi the -nose pad-'arn'f -3 shown as I2. The continuation portions II and I2 may be separate parts soldered or welded to the arcuate arm. I prefer to make such portions integral parts of the bridge and nose pad arm respectively. An endpiece 8 is attached to the temporal end of the arcuate arm I. It should be noticed that the type of attachment of the lens to the lug 2 will allow the lens to pivot slightly upon the securing means. The arcuate arm I tensionally holds of the portions II and I2 overlying the edge of the lens against the edge of the lens on each side of the lug 2 securing the lens in horizontal alignment.

In Figure 4 the edge of the lens 3 is engaged by a continuation of the no e pad arm 6 and by a continuation of the arcuate arm I. In this modification of my invention the bridge I; arcuate arm I, nose pad arm 6 and the lug 2 are assembled at a common junction. The arm 6 extends rearwardly and terminates in a suitable means to attach a nose pad. The other end of the nose pad arm 6 is directed along the arcuate arm I and then redirected forwardly as shownat I2. The arcuate arm I continues beyond the junction of the parts and then is directed forwardly as shown at I3. The other end of the arcuate arm I is directed along the rear surface of the lens and shaped to the contour of the periphery of the lens, terminating at the temporal side in an endpiece 8. The action of the portions I2 and I3 against the edge of the lens secures the lens in ho izontal alignment.

In Figure the edge of the lens 3 is engaged by the flanges I4 and I5 which form the side members of a U-shaped part. The central portion of the U-shaped part is directed along the arcuate arm I and attached so that the center is in substantial alignment with the center of the lug 2. The flanges I5, and I4 can be made as individual units each connected to the arcuate arm. A bridge I0 and the nose pad arm 6 are attached to the nasal end of the arcuate arm I. An endpiece 8 is attached to the temporal end of the arcuate arm I. The action of the portions I4 and I5 against the ed e of the lens secures the lens in horizontal alignment.

The materials used for the several parts may be resilient, pliable, rigid or of any suitable nature. I prefer to make the arcuate arm of a resilient material so t at the parts engaging the edge of the lens will flex when the lens is accidently struck. To provide for this flexing action the arcuate arm is more curved when the lug 2 is not connected to the lens than when it is co nected to the lens.

It is to be particularly noted that the lens edge en aging means are independent of the lug 2 and therefore a most desirable specification of the parts can that the arcuate arm braces the lens edge engaging means; tension of the lensedge engaging means against the'edge of the lens can be regulated by adjusting the arcuate arm.

It can now be seen that I have provided an ophthalmic mounting in which the several objects of my invention are accomplished.

I' have shown and described several of the preferred embodiments of my invention and it is understood that many modifications can be made without departing from the spirit of my invention and that the specification and drawing are illustrative of my invention and not limiting. i a
